ELECTRIC GAS-LIGHTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 389,421, datedSeptember 11, 1888.

Application filed September22, 1887. Serial No. 250,392.

To all whom it may concern:

Be it known that we, \VILLIAM Tao and SANFORD 0. SMITH, citizens of theUnited States,residing in the city and county of Philadelphia, State ofPennsylvania, have invented a new and useful Improvement in ElectricGas- Lighting Devices, which improvement is fully set forth in thefollowing specification and accompanying drawings.

Our invention relates to electric gas-lighting devices; and it consistsin an improved set of electrodes attachable to existing gasfixtureswithout any change or rearrangement ofsuch fixtures. It will be betterunderstood by referring to the accompanying drawings, in which Figure- 1represents a side elevation ofa gas burner with our improvementattached. Figs. 2, 3,and 4.- are detail views of separate parts of ourinvention. Fig. 5 is a detail view of a modified form of expansiblecollar with nut and bolt.

Similar letters of reference indicate corresponding parts in the severalfigures.

A is the gas-pipe, having a burner, B, secured thereto.

0 is the cock,having the usual screw-nut,N, for-holding it in place.

D is a stiff wire affixed to a disk, E, having a hole in its center thesame shape as the small end of the cock, said wire being intermediate ofsaid end of the cock and the burner, and projects from the disk E in theplane of the cook or burner, so as to be between said cock and burner.This wire carries at its upper end a wire electrode, M, adapted tocontact against a fixed electrode, N, held on the burner-tip by a band,G, more clearly shown in Fig. 4, where it is seen that said collar hasan eye, H, and looped end K, to adapt it to anysized tip. The disk E hastwo ormore lugs, L L, adapted to take in any two of thediametricallyopposite holes a a of the washer F, Fig. 3.

'w w are the wires running to the battery. (Not shown.)

To apply these parts to an existing burner we simply spring the band G,carrying the (No model.)

fixed electrode, around a piece of insulating material about the tip orupper end of the burner and pass the free end G of the yoke through theeye H and clasp it, being careful to have the fixed electrode N on theside of the burner next the cock. \Ve now remove the screw-nut N fromthe cock G and place the Washer F, Fig. 3, on the tip of the cock, andthen place the disk E over this with the movable electrode in a positionto be free from the fixed electrode when the gas is turned on or off.Then the nut or screw N is forced down in place, as shown, when thedevice is ready for use. Its operation is obvious and need not bedescribed.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

1. A movable or wiping contact for electric gas-lighters, attached tothe gas-cock by a rod or bar which is substantially parallel with theaxis of the cock, substantially as described.

2. A movable or wiping contact forelcctric lighters, attached to thegascock by an upright rod or barlying always in a plane substantiallyparallel to the cock and the burner, substantially as described.

3. A movable or wiping contact for electric gas lighting devices,attached to a collar adapted to fit over the small end of the gascock,said collar having a lug or lugs, in 00111- biuation with a looseperforated washer to give the electrode the proper angular adjust ment,substantially as described.

4. A movable or wiping electrode for electric gas-lightingdevices,consisting of a spring attached by a rod to the small end of thegascock, and which rod is substantially parallel to the axis of thecock, and provided with means for adjusting its angular position withrelation to the fixed electrode, substantially as described.
